CABLE-CLAMP.

Speeification'of Letters Patent.

Patented 0a. 9, 1906.

To all whom it, may concern;

Be it known that 1, JOHN H. Cook, a citi zen of the United States, and a resident of the borough of Brooklyn, New York cit county of Kings, and State of New Yor have invented a certain new and useful Improvement inCable-Clamps, of which the followin is a specification, taken in connection with t e accompanying drawings, which form a part of the same.

This invention relates to cableclamps, such as are adapted to hold the ends of wire cables by securing the same in grooves in the clamps.

In the accompanying drawin s, in'which the same reference characters refier to similar parts in the several figures, Fi ure. 1 is a longitudinal section of an embo 'ment of this invention, taken alon line '1 1 of Fig. 3. Fig.2 is a similar section taken on the line 2 2 of Figs. 3 and 5. Fig. 3 is a bottom view of one of the clamp members. Fig. 4 is a sectionaLview of the same along the line 1 1,

the bolts being removed. I Fig. 5 is ,a trans verse section of the clamp on the line 4 4 of Fig. 1. Fig. 6 is a partial bottom view of a modified form of clamp member.

In the embodiment of this invention shown forging or in any other way. These clamp members may be given the skeleton construction indicated, the recesses a being formed therein to save material. The clamp members are preferably secured together to operate the same by a series of bolts, which are preferably longitudinally spaced throughout the central bolts D being in 'cated for this urpose,-the

Suitable gripping projections or ribs 1) b, may

also be projected into the grooves to more firmly engage the cable, and these projections are preferably alternately spaced, vas

indicated in Fig. 2, to prevent undue action on the cable. In this way the two grooves in each clamp may cooperate, so as to firmly secure cable ends which may be laterally inortion of the clamp, three serted between the clamping members, if desired. I

In order to more readily apply the clamp, the bolts are preferably permanently secured to the back A,, so that the back and bolts form a single piece. The back is formed with suitable sockets, preferably n0n-circular, so' as to en age the shanks and headsof the bolts an prevent the rotation of the same and also to securely hold them in 'the back, the apertures being so formed as to properly accommodate and grip the particular kind of bolt with whichthey are used. .As'indicated in Figs. 3 and 4, the-back maybe formed with sockets cor-n rising the circular hole 0 to accommodate't e shanks of the bolts and with the tapering outer portions 0, to accommodate the heads D of the bolts. is also referabl formed with portions ada ted to be forced into on agem'ent with the bolt-heads to secure the bolts in position in the back. These portions may take the form of the bolt-holding lugs E E indicated, which are adapted to be driven down upon the boltheads, as indicated in Fig. 1, so as to effectually secure the bolts to the back of the clamp. If desired, however, s uare holes'C The back as indicated in Fig. 6, may be ormed in the .un er disadvantageous circumstances.

Many modifications in the form, size, pro

portions, and numbers of parts may be made in this device by those familiar with the art. Furthermore, parts of this device may be used without employing all of the same and parts may be used in connection with other devices without departing from the spirit of this invention or losing the advantages of the same. I do not, therefore, desire to be limited to the disclosure which has been made in this case; but

What I claim as new, and what I desire to secure by Letters Patent, is set'forth in the appended claims:

1. In a clamp, a back having bolt-sockets and bolt securing portions adjacent said v sockets, .bolts permanently and substantially there being bolt-securing lugs adjacent said sockets, clamping-bolts permanently and substantially non-yieldingly secured to said back by bending said lugs into contact with the heads of said bolts, a cover to cooperate with said back formed with a series of holes for said bolts, said cover and said back having cooperating grooves in their adjacent faces on either side of said bolts and stag gered securing-ridges projecting into said grooves. 1

3. In a clamp, a clamping member having a series of bolt-sockets longitudinally arranged and a series of bolts permanently and substantially non-yieldingly secured in said sockets by forcing down the adjacent portions of said member upon theheads of said bolts 1 after said bolts are inserted in said sockets.

4. A clamp having a back, a bolt-socket in said back, a bolt in said socket, said back being formed with a bolt-securing) forced against the head of said manently and substantially non-yieldingly lug tov be secure the same in said socket.

olt to per-.

non-circular bolt-soc et and with a malleable bolt-securing lug adjacent the edge of said socket to permanently and substantially .nonyieldingly secure a bolt in said socket by being forced against the head of the same.

with cooperating grooves in theiradjacent faces, said back being formed with non-circular bolt-sockets and with malleable portions adjacent said sockets to permanently and substantially non-yieldingly secure bolts theretoby being forced into contact with the heads of said bolts( 7. In a clamp, a back having a series of bolt-sockets, bolts located in said sockets, said back being provided with bolt-securing portions adjacent said sockets to engage said bolts and permanently and substantially unyieldingly secure them to said back, a cover to fit upon said back, said cover being provided with holes to receive said bolts, and said cover and back being formed with longitudinal grooves on either side of said bolts.

8. In a clamp, a clamping member having a plurality of bolt-sockets and a plurality of bolts rigidly secured in said sockets, lugs upon the clampingmembers to engage the bolts and rigidly secure them in their seats.
